Treatment of Herpes simplex virus (HSV) infections

  • Treatment of primary HSV infections: 200 mg five times daily (usually every 4 hours while awake) for 5 – 10 days; patients with keratitis: 400 mg x 5 times/day in 10 days, severely immunocompromised patients or those with impaired absorption: 400 mg five times daily for 5 days, patients with renal impairment (ClCr < 10 mL/min): 200 mg every 12 hours, children aged under 2 years: half the adult dose.
  • Suppression of recurrent HSV infections: 800 mg daily in 2 – 4 divided doses (dosage can be reduced to 400 – 600 mg daily, higher doses of 1 gram daily have also been used); HSV infection in eyes (& eye surgery): 800 mg/day in 2 divided doses; reassessment should be performed after 6 – 12 months of treatment.

Treatment of Varicella zoster virus (VZV) infections

  • Chickenpox: 800 mg four or five times daily for 5 to 7 days; patients with renal impairment have creatinine clearance (ClCr) < 10 mL/min: 800 mg every 12 hours, ClCr 10-25 mL/min: 800 mg three times a day every 8 hours, children (≥ 6 years old: 800 mg, 2 – 5 years old: 400 mg, < 2 years old: 200 mg): four times daily, continue for five days.

Patients with renal impairment associated with HIV experienced hemodialysis: 200-800 mg every 6-8 hours (ClCr 50-80mL/min), every 8-12 hours (ClCr 25-50mL/min), every 12-24 hours (ClCr 10-25mL/min); 200-400 mg every 24 hours (ClCr < 10mL/min); add 1 dose immediately after hemodialysis.


Stacyvir is orally taken.

Acyclovir is contraindicated for patients who develop hypersensitivity to acyclovir or valacyclovir.

  • Renal impairment is usually reversible and may progress to acute renal failure.
  • Increased serum bilirubin and liver enzymes, haematological changes, skin rashes (including erythema multiform, Stevens -Johnson syndrome and toxic epidermal necrolysis), fever, headache, dizziness and gastrointestinal effects such as nausea, vomiting and diarrhoea. Anaphylaxis. Hepatitis and jaundice have been reported rarely.
  • Elderly patients and patients with renal impairment are at increased risk of developing neurological side effects and should be closely monitored for evidence of these effects. These reactions were generally reversible on discontinuation of treatment.
  • Acyclovir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Acyclovir should be administered to a nursing mother with caution and only when indicated.
  • Patients should be aware of how they react to drug before driving or operating machinery.
